side of the solar inverter is
generated.
The solar inverter disconnects
from all PV strings, or the DC
input voltage of all MPPT
circuits is less than 200 V.
The solar inverter is in grid-
tied mode.
If the alarm/maintenance
indicator is red, an
environmental fault at the AC
side of the solar inverter is
generated.
The solar inverter is not in
grid-tied mode.
The solar inverter receives
communication data
normally.
The solar inverter has not
received communication data
for 10 seconds.
